BLACKING-MAGHINE.

To all whom it may concern:

Be it known that I, FREDERICK M. FURBER, a citizen of the United States, residing at Revere, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Blacking-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures. f

This invention relates'to machines for use in finishing boots and shoes and particularly to machines for applying blacking,

stain, sizing or other finishing material, herein referred to generically as blacking, to shoe parts such, for example, as the edges and rands of the heels or soles of boots and shoes.

A general object of the invention is to devise a machine for applying blacking quickly and neatly to shoe parts, particularly to both the edge and rand of a shoe sole. Machines of this type commonly comprise a rotatable edgeblacking device together with a devicewhich acts as a combined rand crease guide and rand blacking means and also serves as a guard to protect Preferably the rand blacking means and edge blacking means'in such machines are mounted for relative displacement in order that the machine may accommodate itself to different types of shoes in which there is a varying depth of rand crease. Blacking is commonly supplied continuously during the use of the machine and in case of interruptionof work, the blacking may accumulate in considerable quantities so as to interfere with the proper operation of the machine when work is again applied thereto;

With a view to avoiding the difficulty above discussed, features of the invention 'cons1st 1n a machine organization 1n which the fiow of blacking to one or both of the blacking devices is controlled by relative displacement of the blacking devices. In the illustrated machine the application of work to operative position relative to the machine controls the flow of blacking.

Another feature of the invention consists in the provision of a machine especially designed for blacking the edges and rands of shoe soles in which both the rand and Specification of Letters Patent.

the edge blacking means are positively rotated to insure a proper supply of blackin the construction and. arrangement being such that one of the blacking devices may pass through the bottom of the receptacle without the necessity for a packed joint.

The preferred construction of such a machlne will be described in the following specification taken in connection with the accompanying drawings, in -which,

Figure 1 1s a side elevation, partly in sect1on, of my improved machine; and

Flg. 2 1s a perspective, partly in section, of the rand blacking means.

Bolted to the column 10 is a frame 12 in which is journaled a shaft 14 which is adapted to be connected to the driving pulley 16 bythe operation of a clutch lever 18 which, in the particular arrangement shown, comprises cam surfaces 20 for engaging the clutch members 22 against the tension of the spring 24.

Mounted on the upper end of this frame 12 is a blacking receptacle 26 provided With a cover 28 and with a stirrer 30, constructed as a spider with depending arms, which is bolted to the upper end of a shaft 32 journaled in the frame 12 and passing through a sleeve 34 risingupward from thebase of the receptacle and preferably constructed integrally therewith. The height of the,

shaft 14 cooperates with a gear 38 to drive i the stirrer shaft 32.

A sleeve 40 formed in. a bracketi42 upon .theframe 12 serves as a bearing for a hollow shaft 44 which is positioned in the sleeve by means of a collar 46 and a worm gear 48. This gear meshes with'a worm 50 mounted on the shaft 14 and serves as Patented Apr. 5 1921. Application filed January 22, 1917. Serial No. 143,799.

rand blacking means is allowed.

means for driving the hollow shaft to which the gear is attached by means of a screw 52.

The-gear 48 is formed with a sleeve eXten- V structed with a perforated circular guide 7 58. between the rows of bristles to prevent their depression within a fixed periphery. At the same time theperforations in this guide allow the flow of blacking from one row of bristles to the'next.

Arranged concentrically with the edge blacking brush is a frusto-conical combined rand crease guide and rand blacking means 60. r This rand blacking device is preferably constructed in the manner more clearly shown in Fig. 2, from which it will be seen that a chamber 62is provided within the rand blacking device. This chambercommunicates wlth one base of the frustum,

i here the upper surface, by means of an annular groove or opemngtei and wlth the other base by perforations 66. The device is preferably provided with bristles 68 mounted in a wall of the chamber 62 and within a recess within the lowerbaseof the guide and interposed between the perforations 66. Thus the perforated wall of the chamber may be said to constitute the back 7 of the brush. This rand blacking device is mounted on a shaft 70 within the hollow shaft 44 and mechanically connected for simultaneous rotation therewith by means of a universal joint 72 by reason of which relative movement offthe edge blacking and The 1101- low shaft 44: is constructed with a conical socket 74 on its interior which cooperates with a ball-shaped member 76 slidably mounted upon the shaft 70 and pressed into the socket by a spring 78. This latter arrangement tends to move the two blacking devlces into concentric relatlon but does not A. nozzle 80 is pivotally mounted in a bracket 82 formed on the receptacle 26 and is provided with a channel 84 connected to the receptacle 26. by means of a flexible tube V i 86. A thumb screw 88 allows'for regulation of the size of the channel 84 thereby to 0011- trol the flow of blacking. The nozzle is held in engagement with the upper surface of the rand blacking device 60 by means of a spring 90. Preferably, the upper surface of the rand blacking device 60 is slightly spherical and the lower surface of thenozzle is correspondingly recessed in order that the nozzle may be held inclose contact with the upper surface of the rand blacker and prevent leakage of blacking. The opening in the lower end of the nozzle is so designed that it may be closed by the end surface of hub 92 of the rand blacking device when the however, as the rand blacking device is displaced laterally or from concentric relation.

'with the nozzle 80 and the edge blacking brush 56, therewill be a flow of blacking through the annular groove 64L into the chamber 62 and thence through the perforations 66 and the perforations in the guide 58to all parts of the rand blacking device and the edge blacking brush.

The edge of the sole will be presented to the blacking machine in the manner indi-' cated in Fig. 1 so that the sharp edge of the rand blacking device 60 enters the rand crease. The work is then still further advanced until the edge of thesole contacts. with the edge blacking brush 56 with a resultingrelative displacement of the two thus causing a flow of blacking through the annular groove 64 to the two blacking devices. No blacking is delivered to the upper surface of the rand blacking device 60, however, and this arrangement alsoserves as a guard to prevent soiling the upper. The guide '58 in the brush 56 prevents too great a depression of the bristles of the brush 56 by the application of work. It will be noted that by means of this arrangement, blackingis supplied only at the time of the application of work and it is immediately shut off upon the re movalof the work by reason of the action of the springpressed ball 7 6 in returning the rand blacking device 60 to its central position. The volume of flow may effectively be controlled by manipulation of the thumb screw 88. During the operation of the machinethe blacking in the receptacle 26 is constantly adjusted by rotation of the stirrer 30.

While I have herein described this machine particularly with reference to its use in applying blackingto the rand and edge of a shoe sole, it will be understood that it may readily be applied to other parts of a shoe and its use is not limited to this particular 2.
